observation
Quick Summary
Observation is the act of noticing or perceiving something, often involving careful measurement and recording of facts or occurrences. In science, observation is a fundamental method for gathering information about the natural world. This can range from observing customs and laws to noting scientific phenomena.12
Scientific observation can be done directly, such as with naked-eye astronomy, or indirectly through instruments like telescopes. Space exploration has greatly expanded our ability to observe, allowing scientists to gather data about Earth, the solar system, and the universe that would be otherwise unobtainable. These observations can be made using robotic spacecraft or human crews. Analyzing physical samples, like meteorites or moon rocks, is another form of scientific observation that complements remote sensing. The goal of scientific observation is to identify patterns, correlations, and ultimately, to develop and test theories about how the universe works.3245
